From the early Church Fathers to now.
“And Esdras the priest stood up, and said to them: You have transgressed, and taken strange wives, to add to the sins of Israel.”
“Assuredly also, when (the apostle) rules that marriage should be "only in the Lord," (1 Cor. 7:39) that no Christian should intermarry with a heathen, he maintains a law of the Creator, who everywhere prohibits marriage with strangers.”
“And Ezra the priest arose and said, etc. This passage corresponds to what was previously mentioned: And Ezra arose before the house of God and went to the chamber of Johanan the son of Eliashib, and he went there, he did not eat bread, and he did not drink water; for he was mourning. Here the devotion of the high priest is to be noted, who, mourning, praying, and fasting for the transgression of the people, remained for three days in the courtyards of the temple; nor did he wish to enter his own house before he saw the people, having given their consent, wholly repentant and turned to the Lord with all their heart. The other leaders also seem to have shared in his devotion, as they are said to have gone to the houses of their fathers after the assembly was finished. For if the sacred history writer did not wish to signify this with that statement, what was the point of writing that, after the discussion was completed, Ezra and the heads of the families went from the courtyards of the temple to the houses of their fathers, when everyone would know that they would do this even without Scripture saying it? What was the point of adding, And all by their names, when this too would be well-known to all, except that he wanted it to be understood that they were such whose names and deeds should rightfully be kept in memory and handed down to be known by posterity?”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
